CLOTH-TREATING APPARATUS.

To ali/whom 'it 'may concern:

Be it known that I, DAVID GEssNER, a citizen of the United States, and a resident of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Cloth-Treating Apparatus, of which the following is a specification.

My invention relates generally and broadly to new and useful improvements in cloth treating apparatus and more particularly to apparatus of that character or type adapted to subject cloth in bulk to what is known as the wet process in which the cloth is treated with hot or cold water or steam in order to setthe cloth and arrest shrinkage, so that subsequent shrinkage of the cloth when passing through the dyeing or other process will be reduced to a minimum.

The object of the present invention is to provide an apparatus for carrying out the wet process adapted for the treatment of cloth in a substantially cylindrical hollow roll by a continuous circulation of water which may be hot or cold and which will include means for subjecting the cloth roll to suction in order to remove the water, or other liquids, therefrom, whereby the removal of the water from the cloth is accomplished by the same apparatus which performs the wetting` treatment, and the subsequent removal of the water by other stepsV or means is obviated.

The invention consists in the improvements -to be fully described hereinafter and the novelty of which will be particularly pointed out and distinctly claimed.

I have fully and clearly illustrated my invention in the accompanying drawings to be taken as a part of this specification and wherein- Figure 1 is a view in central longitudinal vertical section .through an embodiment of my invention showing a roll adapted to carry cloth, in position with the separable bearings therefor disengaged therefrom. Fig. 2 is a view similar to Fig. l showing Fig. 3 is a longitudinal section through the end of the apparatus appearing to the right of Figs. 1 and 2. Fig. 4 is an end elevation of the apparatus showing the driving means for the roll. Fig. 5 is a side elevation of the Specification of Letters Patent.

.Application filed April 21, 1910.

serial No. 556,781.

driving means shown in Fig. 1. Fig. 6 is a View in elevation of the end of the apparatus opposite to that shown in Fig. 4. Fig. 7 is a detached perspective view of an adjunct of one of the bearings for the cloth receiving or carrying roll. Fig. 8 is a detailed plan 'View of one of the cloth roll bearings in engagement with the roll and showing means associated with the bearing for engaging the roll to move the latter lengthwise with the bearing. Fig. 9 is a similar view to that shown in Fig. 8, with the roll separated from the bearing. Fig. 10 is a detailed sectional view of the water circulating pipe shown in Fig. 3.

Referring to the drawings by numerals 'of reference: 1 designates a vat or vessel which is substantially oblong in plan and formed with side walls 2, 2, end walls 3, 3, and a transversely curved bottom 4, said vat being of any suitable material and of such dimensions and contour as to suit for the purposes for which it is einployed.- This vat is designed to receive a roll of cloth carried on a hollow cloth receiving roll and to contain water or other liquid for treating the roll of cloth, means being provided within the vat for supporting the cloth roll out of contact with the walls thereof, for establishing a circulation of liquid through the cloth roll, and for subjecting the roll to suction to remove the liquid therefrom.

One of the end walls 3 of the vat is formed with a circular opening 5 having a reinforced edge, in which opening is seated a closure plate 6, which may be secured in place by any suitable means, not shown. This closure plate G is formed with a central opening' 7 which receives a bushing 8 through which projects a bearing thrust shaft 9, one end of which projects into the vat and carries a bearing to be described presently. The portion of the shaft 9 exterior of the vat is reduced as at 9, to form a shoulder 10, and on the reduced end 9 is a threaded sleeve 11, said shaft and sleeve projecting through a threaded bushing 12 rotatably mounted in a four-arm yoke 13 rigidly mounted on the outer face of the closure plate 6, said bushing heilig manually rotatable by a hand wheel 14 keyed thereto. The sleeve 11 is held on the shaft against movement longitudinally thereof by said shoulder 10, a stop collar 15 for a purpose to presently appear being` clamped between the sleeve and said shoulder, and a nut and washer 16 threaded onto the outer end of said shaft. In order to prevent rotation of the sleeve 11 on the shaft, said sleeve is formed with a longitudinal groove 17 which receives a fixed guiding piece 18 rigidly mounted on the yoke 13.

From the above itY will be seen that by rotating the hand wheel 14 the bushing 12 will be rotated to feed the sleeve 11 and shaft 9 back and forth according to the direction in which the wheel is turned. The bushing 8 may be provided with an oiling duct 19 by means of which lubricant may be fed to shaft 9 to lubricate the same. Said bushing is also provided with an exteriorly threaded neclr 20 yproject-ing within the vat and adapted to receive a threaded Vpacking nut 21, between which and said neck is a packing 22, serving to prevent leakage of the Huid in the vat between the shaft and bushing.

1t will be noted that the shaft 9 can be rotated in its bearings formed by the bushing 8 and the sleeve 11, and at the end of the shaft within the vat the same carries suitable means for so supporting the end of a cloth roll that the shaft turns with the roll when the latter is rotated by means to be described hereinafter. At said inner end the shaft 9 is provided with a head 23 formed with a pocket 24 and seated in said pocket is a two-part poly-faced sleeve 25 having a lower projecting wall or shelf 26 which extends out for a distance beyond the eXtreme inner end of the head 23. Seated in the bottom of the pocket 24 is a centering pin which cooperates with the cloth roll to center the same, in a manner to be presently set forth. rllhis pocket 24 is designed to receive a poly-sided head 23 on the head 29 of a hollow perforated cloth receiving roll 30, whereby one end of the roll is supported and causes the shaft 9 to turn therewith. The connection between the shaft and roll is the same as that covered by my co-pending application Serial No. 446,953, filed August 1903. Also carried by the inner face of the closure plate 6is a shelf member 31 located below the shaft 9, and carrying` pairs of ears 32, one located on each side of the shaft, as shown in Figs. 3 and 9, in which are secured pins 33, upon which turn loosely anti-friction rollers 34, said rollers being arranged with their aXes of rotation parallel to the axis of the shaft. rlhe cylindrical head 23 on the shaft 9 rests upon these rollers, the element 31 thereby serving to support the shaft, and the rollers 34 providing for the easy rotation of the head 23 on the support.

The end of the support or shelf 31 carries a safety shelf member 35 projecting out beyond the elements 23 and 23 to take position beneath the adjacent end of the cloth roll to catch the latter should an attendant,

roll resting clear of the shelf when the parts are in the condition shown in Fig. 2, when the head and socket are properly engaged.

From the description so far given it will be understood that by manipulating the hand wheel 1 4 the sockethead may be moved bach and forth with the shaft 9, and that by this means the soclret head 23 and the head 28 are separated, the movement of the shaft and head outward being limited by the stop collar 15 abutting the projection 13, on the yoke 13.

As will be hereinafter described the end of the cloth receiving roll opposite to that carrying the head 23 is adapted to detachably engage a bearing member, and 1 will now describe means associated withk the shaft 9 for imparting a longitudinal movement of the cloth roll to separate the same Afrom this bearing whenever the shaft 9 Vis moved outward. rfhe head 23 heretofore described is formed with a circumferential groove 36 adapted to receive a bead or flange 37 formed on the inner face of a saddle element 33 which rests upon the saidrbead, said element having opposite, laterally disposed arms 39, which slidably engage parallel guide bars 40 rigidly mounted upon the inner face of the closure plate 6, the said arms being formed with guide openings to receive said bars 40. The connection between the saddle element and the bars 40 provides simple and effective means for preventing rotation of the saddle element on the head 23. Preferably formed integral with the saddle element is a vertically eX- tending bracket 41 having spaced ears 42 between which is pivoted an engaging member 43, adapted to engage the cloth roll and move the same with the `head 23, said member beingl preferably in the form of a hook to engage over an end iiange 29a on the head of the cloth receiving roll.v By this provision means is afforded for positively moving the cloth receiving roll to draw it from its bearing at the end opposite to the head 29.

Means is provided for limiting the movement of the cloth roll by the shaft 9 and member 43, a convenient and simple provision being a shoulder 35a on the upper surface of the shelf part 35. This shoulder is so located that when the shaft 9 has been sufficiently retracted the cloth roll will engage said shoulder, and then after the hook 43 has been detached from the roll the shaft may be further retracted until the stop col- 44 closed by a closure plate 45, the latter also having a central aperture 46 surrounded by annular flanges 47, 48, on said plate, the

former projecting within the vat and the latter exterior thereto, said flanges forming a cylindrical bearing. Extending through this cylindrical bearing just described, is a hollow shaft member 49, the same being spaced from the inner face of the bearing by suitable packing sleeves 50, 51, the latter projecting within the flange 47 and having a conical seat 52 to receive packing 53, surrounding the hollow shaft, said packing being compressed and held in place by a packing collar 54 also surrounding the shaft and bolted to the plate 45 as shown at 55. At its end within the vat the shaft 49 is provided with an end head or plate 56 preferably cast integral therewith to which is bolted a cylindrical shell 57, said shell being open at its inner end and formed with an internal annular flange 58 carrying suitable packing 59 on its outer face. The open end of this shell 57 is adapted to receive the end of the cloth carrying roll opposite to that provided with the head 29, said roll being adapted to abut the flange 58. The roll may be provided with a circumferential flange 30b to engage said flange 58 and form a water-tight joint between the same. rIhis shell 57 is of greater diameter than the cloth carrying roll and they are so related when the flanges 30h, 58, abut as to be concentric with each other so that in any position of rotation of the chamber and roll the lowermost portion of the chamber will be below the1 low-ermost portion of the body of the rol The hollow shaft and the chamber 57 are arranged to be rotated so as to turn the roll 30, and suitable gearing acting upon the said hollow shaft is employed for this purpose, said gearing being preferably constructed and arranged as follows: Rigidly connected to the end of the vat is a horizontally disposed platform bracket 60, upon which is detachably mounted a vertical bearing supporting member 61, to one vertical edge of which is detachably bolted a bearing bracket 62, carrying a bearing 63 for one end of a driving shaft 64, the opposite end of which turns in a bearing 65 in a bracket 66 connected to the vat. Upon this shaft mounted to turn therewith is a belt pulley 67 adapted to be connected by a belt-not shown-with any suitable source of power, and also on this shaft is a loose pulley 68. The belt may be shifted from one to the other of these pulleys by a belt shifter slidably supported on a bracket arm 69 on the bracket 60. The belt shifter consists of two spaced rings 70, mounted on a block 71 which is bolted to a second block 72, which latter block is dovetailed onto the bracket arm 69. The rings 7 0 may be braced and held in spaced relation by means of a spring bar 73 between said rings and secured thereto by screws 74. I employ this form of belt shifter for the reason that I am enabled to apply the driving belt to the pulley from practically any angle which is of advantage in that the apparatus may be conveniently installed in a mill or factory without the necessity of altering an established line of shafting. The belt shifter may be operated by a hand lever 75 fulcrumed on the floor as at 76, and connected to the block 72 by a connecting rod 77. Keyed to the shaft 64 is a pinion 78 which meshes with a gear 79 on a counter shaft 80, the ends of which shaft respectively have bearingl in a bearing 81 in the end of the vat, and a bearing 82 in the element 6l. This shaft carries a pinion 83 which meshes with a gear wheel 84 on the hollow shaft 49.

From the above description taken in connection with the drawings, it will be apparent that whenever the belt-shifter is operated to place the belt upon the fixed pulley 67, through lthe gears 78, 79, 83 and 84 the hollow shaft 49 and the chamber formed at the shoulder' 57 will be rotated which will in turnr operate to rotate the cloth-carrying roll 30.

Means is provided for introducing water or steam, or both, through the hollow Shaft 49 into the chamber formed by the shell 57, whence it may flow into the interior of the clotlrcarrying roll to moisten the roll from the interior thereof. The means for accom* plishing this result, while capable of wide variation, consists preferably of a -pipe 85 extending longitudinally through said hollow shaft and terminating at its end portion within the chamber formed by the shell 57, the outer end of the pipe being connected by any suitable means, not shown, to a source of water supply. A suitable pump, not shown, or other circulator, is employed for causing the circulation of water in either direction through the pipe 85. At its inner end within the chamber 57 the pipe 85 is provided with a head 86 having a depending hollow extension 87, the lower end of which projects below the lowermost level of the cloth receiving roll 30, while the latter is connected to the chamber 57. The wall of the head 86 opposite to the opening in the Aend of the pip-e 85 is'provided with an open- -mfg 88 closed by a valve 89 having a hollow valve stem 90 guided in a spider 91 threaded into aflange 92 -onv the head S6. This valve 89 is rigidly Aconnected to a steam pipe93arranged within and extending longitndinallyof the pipe 85 and connected to a :suitablesource of steam. not shown. This pipe is movable longitudinally of the pipe 85 and is connected 4at its inner end to the valve 89 withthe hollow stem of which it communicates, the arrangement being such tlratnthe pipe-93 may be moved to seat the valve89fa2s shown infFig. 3, or to unseat it aseshown in Fig. l0. The opening 88 is provided within theihead 86 in order that a flow of watermay pass directly into the interior of Lth'e roll 30, while the wetting of the roll-istakinglplace, while the neck 87 is adapted tol draw water from the roll which iniayfiow into the interior of the chamber 57-when the circulation of water through the vat is `cut olf and it is desired to reverse the flow through the pipe v86 to draw moisture from the roll.

Suitable -means may be employed for properly packing the space between the interiorA of the shaft 49 'and the exterior ofthe pipe 85 toprevent leakage of water, said Ymeans consisting of a flanged packing collar 94` surrounding pipe 85 within the chamber 5711and bolted tothe head 57 'by bolts 95, suitable packing being employed between the packing vcollar 94 and a shoulder in the shaft 419, all as clearly shown in Fig. 3 of the drawing.

,Iprefertoconstruct the chamber 57 as heretofore described in ord-er that the parts associated Twith the ends of the steam and the water pipes may be readily accessible for adjustment or repair in order that the packing between the shaft 49 and pipe 85 may be conveniently reached when desired.

Mounted within the vat at a point closely ladjacent the inner end of the chamber 57 is a support adapted-to receive the end of the cloth-receiving roll whenever said roll is withdrawn `vfrom its connection with t-he chamber 57, so that said end will be held against dropping` downwithin the vat. This means consists of a vertically disposed plate member 96 adjustably supported at its lower edge upon bolts 97 .let through sleeves 9S in the bottom of the vat, the outer open ends :of thesleeves being closed by plugs 99 to 1letthrough sleeves in thee-ide walls ofthe vat 1and closed by v,plugs 104. rlhe upper edge of the plate member 961is formed in an'arc of the same radius asthe-tlange 30" as at 105, which flange 301 engages with the flange 56 on the chamber 57, the arceshaped seat on said plate member 96 being adapted to receive the flange 301) to support that end of the roll when the latter is separated vfrom the chamber and supporting member 56. By means of the bolts 97 which support the plate 96, said plate may be adjusted vertically so as to bring said arc-shaped seat slightly below the internal surface ofthe member 57, so that when the roll 30 is moved lengthwise under theiniu'ence ofthe hand-wheel ll, the flange k30b will Vpassito said seat 105.

The bottom ofthe vat is formed with a longitudinally extending trough 106, one ofthe purposes of which is to receive any sediment or foreign particles which may lcollect in the vat duiiing the wettingprocess .and said trough is provided with an outlet 107 through which the sediment may be drawn off. Arranged within this trough 106 is a short piece of longitudinally extendingfpipe 108 through which water, or othertreating fluid, may be. introduced or drawnfrom the receptacle,said pipe being supported at one end in a plug 109 which closes an opening in the end wall of said trough. Alsoprojecting tirough the plug and extending through the water pipe just described isa smaller pipe 110 through whichsteam-may be passed into the vat when it is desired to heat the cont-ents thereof. These pipes are located wholly within the trough-so that there is no projection extending above the main body portion of th-e bottomofthe vat to interfere with the manipulation of the roll, as will be set fo-rthpresent-ly.

Adjacent the ends of the vat :I may provide bridge pieces 111 of a .desired `width which connect the side portions of the bottom of the kettle on either side of .the trough 106, the upper surface. of said bridge pieces being substantially continuous with the Aside walls andcurved bottom of the Lkettle so that a smooth and continuous surface,` is provided, over which a flexible lifting band or bands may pass slidingly without being caught by having its passage obstructed by the walls of the trough 106, or the pipe located therein. rlhese lifting bandsusually consist inpartof flexible metal which Vare passedaboutthe roll by insert-ing one end from the side ofthe vat andpushing upon the body of the band until the inserted end portion emerges from between the roll kand the opposite side of the vat, the end ofthe bands being guided by the inner surfaceof the vat.

Having thus described one embodiment of my invention l will now set forth briefly'the i completeoperation thereof fromthe time a roll of cloth is inserted therein until itis. removed after being treated. vtroll ofcloth having been formed upon one of the winding machines which have formed the subjectmatter of other applications filed by me, upon t-he roll 30, the latter is placed within the vat 1, so as to rest at one end upon the plate 96 and at the other end upon the sup- -porting shelf 20, the socket head 23 having i roll having been inserted as just described,

the hand Wheel 14 is operated in the proper direction to move the shaft 0 and the head 23 toward the cloth roll, the head 23 being supported throughout its movement upon the friction rollers 31 mounted on the bracket 31. This movement continues until the head 28 is secured Within said head 23, the pin 27 entering said head Q8 to center the roll 2:30, and the movement of' the head being continnous, the roll 30 is moved longitudinally toward the chamber 57 until the flange 50b enters the open end of said chamber and is seated against the flange 5S forming a fluidtight joint between said roll and said ch-.nnber. This operation of course serves to move said flange 30b from the seat 105, so that this end of the roll is no longer supported by said seat, and it will be understood that ailter'the completion of this operation just stated the roll 30 is supported entirely by the head 23 and the chamber 57 and is free to rotate Without engaging any of the other parts ot' the vat or the elements therein. lVatcr at suitable temperature can then be pumped through the pipe 85 into the interior of the chamber 57 and the valve opening 88 in the end of the head 86, the valve having first been operated to open said port 8S. he Water injected through the pipe S5 flows within the perforated cylinder 30 and when the latter is rotated by means of the gearingdescribed the Water is permitted to pass through the perforations in the cylinder to the internal folds of the cloth and find its Way outward through the roll. It Will be understood that before this operation takes place the outlet 107 is closed. This operation continues until the vat is filled with water and the cloth roll submerged, after which the outlet through the Water pipe 108 is opened and the pump of the circulatory system is set in operation to circulate Water through the vat, the Water passing through the pipe out through the roll into the vat and thence out of the vat through the pipe 108.

The construction which I have described provides :tor the water being passed through the cloth from the exterior thereof into the roll 30 and out through the pipe 85 with equal facility to the operation just described. When it is desired to so treat the cloth, the flow is reversed and the pipe 93 is operated to close the valve opening 88, so that suction is created by the pump in the pipe S5 and the water is drawn through the roll into the chamber 57 through the neck 87 and out through the pipe S5. It, at any time, it should be desired to heat the water, steam may be admitted through either the pipe 03 or the pipe 110, as may be desired.

When the wetting process has been completed and it is desired to remove the moisture from the roll, the pipe 108 is cut off from the circulatory system, the outlet 107 may be opened to permit the water to drain from the vat. The valve 89 is then closed,

'and suction being` created in the pipe 85,

Water which is in the cloth will be drawn inwardly into the roll 30 whence it Will flow into the chamber S7 and pass therefrom through the neck S7 and to 85. It will be` understood that during this operation the roll is continuously rotated, so that themoisture will be drawn equally from all partsthereof. The extraction of' the moisture having been carried on to the proper degree the circulatory system, or such part thereof as has been used in the extracting process is cut ofi:1 and the hook or connecting member 43 is swung to engage over the flange 29 on the end of the cloth-receiving roll. The operator then turns the hand Wheel 14 in the proper direction to retract the shaft f) which moves the head 253, the connecting member 43, and the clothcarrying roll longitudinally until the flange 29 on said roll engages the shoulder on the supporting bracket this shoulder serving to arrest further movement of the roll. In this position the roll is supported at one end on said shell 26 and at the other end is supported by its flange 30" upon the seat 105 on the supporting plate 96, said latter-mentioned flange having been Withdrawn from engagement with the chamber 57. The hook member 43 is then disen- Aaged from the roll and the hand-Wheel is turned still farther in the same direction to continue the movement of the socket head Q3 so as to disconnect its square pocket from the head 28 upon the end of the roll 30 while still leaving' the head Q8 resting upon the shelf 26. The parts having been operated to take this position, both ends of the roll are thus freed, so that the roll may be engaged bv a proper lifting means to lift the same from the vat. The vat is then in position to have another roll ofcloth inserted therein for treatment and the operation may be repeated.

l have shown and described with considerablc particularity a detailed construction which T deem desirable in order to produce an eilicient and conveniently-operated machine, but I do not desire to be limited to thc exact details shown and described as l may alter the same as occasion may require, without departing from the spirit and scope of my invention.
